Contribució al coneixement dels copèpodes (Crustacea) meiobèntics de la costa de Sardenya, Itàlia Les dades disponibles sobre espècies italianes de copèpodes Canuelloida Khodami, Vaun MacArthur, Blanco-Bercial i Martínez Arbizu, 2017 i Harpacticoida Sars, 1903 registren un total de 210 espècies, però la seva diversitat i la seva biogeografia continuen estan escassament investigades. Vam portar a terme un estudi faunístic a la costa est de Sardenya (regió d’Ogliastra) a fi de documentar-hi la presència d’aquests taxons. Hi vam trobar un total de 41 espècies de 36 gèneres i 18 famílies. Tot i que moltes espècies es van identificar com a putatives, la llista de control italiana vigent va ser actualitzada amb 12 registres nous de gèneres i quatre d’espècies. Longipedia coronata Claus, 1862 (Canuelloida), Diosaccus tenuicornis (Claus, 1863), Asellopsis hispida Brady i Robertson, 1873, Wellsopsyllus (intermediopsyllus) intermedius (Scott i Scott, 1895) (totes Harpacticoida) van ser registrades per primera vegada a les costes de Sardenya. La comunitat de copèpodes va resultar particularment rica a l’illa d’Ogliastra, un illot rocallós amb esculls naturals, bancs de roques i praderies de Posidonia oceanica. Les espècies trobades a la zona estaven relacionades principalment amb sorres gruixudes i detritus macròfits. Dades publlicades a GBIF: doi:10.15470/dxru6l

This study documents for the first time the taxonomic composition of the nematode community and the number of free–living nematode species in Lake Varano, Southern Adriatic Sea, Italy. The nematode community was mainly composed of species typical of fine sediments that usually prevail in transitional environments (TEs). An overall high number of nematode species was recorded (55), belonging to 36 genera in 17 families. These values are highly comparable to those reported for other Italian TEs, but appear lower than those recorded in other European brackish–water systems, probably in relation to the low salinity range of Lake Varano. Forty taxa were identified up to species level, thus increasing the number of the nematode marine species known for the Italian coasts from 443 to 463, for the Adriatic basin from 310 to 313, and for the Southern Adriatic sector from 37 to 77. Considering the importance of this phylum in the assessment of ecological quality and the great vulnerability of the Adriatic Sea ecosystems, an intensification of sampling efforts should be planned, especially in the Central–Southern part of the basin. Such a plan would provide new insights into the biogeography of one of the most important components of the benthic domain and potentially yield new information about the climate warming effects on the Adriatic Sea.

The detection of lard in food products is of special interest for reasons of quality, dietetics or religious belief. Works carried out to date have mainly concerned fatty mixtures with others food components. This work studies a complex food products (dehydrated stock model) containing hydrogenated palm and beef fat. An appraisal is carried out regarding the detection sensitivity to the addition of 0.2% lard, using data on sterols and fatty acids in the β position. This last model only appears reliable for the goal proposed.
